Multiple Caliber Sound Suppressor With Adapter For Use With Muzzle Accessory

Abstract

A system for installing a first muzzle accessory on a barrel of a firearm having a second muzzle accessory mounted thereto comprises an adapter configured to attach to the second muzzle accessory and a first muzzle accessory configured to attach to the adapter. The adapter serves to temporarily deactivate the second muzzle accessory when the adapter is attached to the second muzzle accessory.

Having thus described the aforementioned invention what is claimed is: 
     
         1 . A system for installing a sound suppressor on one of a plurality of firearms, each firearm having a muzzle accessory mounted thereto and each firearm being of a different projectile caliber, the system comprising:
 an adapter configured to attach to the muzzle accessory; and   a sound suppressor configured to attach to the adapter, the sound suppressor comprising:
 an outer housing having a generally cylindrical shape and an open forward end; and 
 a plurality of forward walls removably securable to the forward end of the housing and interchangeable with one another, each of the forward walls defining a through bore positioned along the forward wall to align with a central axis of each of the muzzles of the firearms when the forward wall is secured to the housing, each through bore conforming to the caliber of one of the firearms. 
   
     
     
         2 . The system of  claim 1  further comprising a coupler configured to attach to the adapter, the sound suppressor configured to attach to the coupler. 
     
     
         3 . The system of  claim 1 , wherein the adapter is configured to limit air flow within the muzzle accessory to between a projectile intake and a projectile outlet of the muzzle accessory, whereby the muzzle accessory functions as an expansion chamber for gas exiting the muzzle. 
     
     
         4 . The system of  claim 1 , wherein the adapter comprises a sleeve configured to surround at least a portion of the muzzle accessory. 
     
     
         5 . The system of  claim 4 , wherein the adapter further comprises a chuck configured to engage the muzzle accessory to secure the adapter to the muzzle accessory when the muzzle accessory is received within the sleeve. 
     
     
         6 . The system of  claim 5 , the chuck comprising at least one cutout defined along the sleeve, and at least one movable segment member removably received within the at least one cutout. 
     
     
         7 . The system of  claim 7 , wherein the at least one movable segment member defines a surface configured to mate with and engage at least a portion of at least one feature of the muzzle accessory. 
     
     
         8 . The system of  claim 8 , wherein the at least one movable segment member is rotatably secured to the sleeve within the at least one cutout. 
     
     
         9 . The system of  claim 7 , the chuck further comprising a fastener for securing the at least one movable segment member within the at least one cutout. 
     
     
         10 . The system of  claim 10 , wherein the fastener is a threaded fastener. 
     
     
         11 . The system of  claim 11 , wherein the fastener establishes an engagement with the at least one movable segment member and a frictional engagement with the sleeve. 
     
     
         12 . The system of  claim 1 , wherein each forward wall defines a threaded outer surface adapted to threadably mate with an inner surface of the housing and at least one protuberance configured to be engaged for rotating the forward wall into and out of threadable engagement with the housing inner surface. 
     
     
         13 . The system of  claim 12 , each protuberance being defined by a removable bolt positioned along a forward surface of the forward wall. 
     
     
         14 . The system of  claim 1 , wherein each forward wall defines a rearward surface configured to face an interior of the housing and defining an annular concave trough encircling the respective through bore of the forward wall. 
     
     
         15 . The system of  claim 14 , each forward wall rearward surface further defining a truncated conical deflector portion annularly surrounding the through bore of the forward wall and extending between the through bore and the annular concave trough. 
     
     
         16 . The system of  claim 1 , wherein the plurality of forward walls include forward walls having through openings conforming to each of a plurality of calibers.
